After the apparent death of the rest of all of the Autobots, Dinobots, and Maximals, Unicron's minions ravage the Earth in preparation of his arrival. Katie, Billy, Sean and Emma try to hold out in hopes that maybe some survived. While fiddling with Bumblebee's parts, since his car still runs, she pushes another bolt into it's right place, reactivating Bee and giving him his memories back. Bee is now the last hope for humanity.
